Product Details

The ADRF5720-EVALZ is a 4-layer evaluation board. Each copper layer is 0.7mil (0.5 oz) and separated by dielectric materials.

All RF and dc traces are routed on the top copper layer whereas the inner and bottom layers are grounded planes that provide a solid ground for the RF transmission lines. Top dielectric material is 8 mil Rogers RO4003, offering good high frequency performance. The middle and bottom dielectric materials are for providing mechanical strength. The overall board thickness is 62 mil, which allows for 2.4mm RF launchers to be connected at the board edges.
